Description
The device is designed to count the number of radio components in the SMD tape. The counting is based on an optical principle using an optocoupler. The project was developed as a training project for working with STM32F103 microcontroller peripherals. The device uses the basic peripherals such as: GPIO, interrupts, timers, I2C, ADC, etc. I also used the state machine pattern. The firmware is written with CMSIS. The circuitry of the device and the PCB were also developed. The case was modeled and 3D printed.
